LEONARD L. WILLIAMS, OF NAUGATUCK, CONNECTICUT, ASSIGNOR OF ONE-HALF TO D. P. MILLS, OF SAME PLACE.

CARDlNG-ENGINE.

SPECIFICATION forming part of Letters Patent No. 425,091, dated April 8, 1890.

Application filed May 11, 1889. Serial No. 310,465. (No model.)

To all whom it may concern.-

Be it known that I, LEONARD L. WILLIAMS, a citizen of the United States, residing at Naugatuck, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Carding-Engines, of which the following is a specification.

My invention relates to improvements in carding-engines; and the object of my improvement'is to furnish simple and practical means for returning the imperfect rovings to the second breaker to be recarded.

In the accompanying drawings, Figure 1 is a side elevation of so much of two cardingengines as is necessary to show my improvement. Fig. 2 is a plan view of the same; Fig. 3, an end view; Fig. 4, a detached side elevation of the adjustable shell or guide, the same and the following figures being on a larger scale than the preceding figures. Fig. 5 is a plan view of the same. Fig. 6 is a detached side elevation of another guide, and Fig. 7 is an edge view of the same.

A designates the framing of the second breaker, and B that of the finisher. Each of these is provided with a main cylinder 8, with the usual appendages, while the finisher is provided with rub-rolls or condensers 9 and 10, from which the rovings are delivered to any suitable receiver. The material from the second breaker passes to the finisher in the form of a large roving 11, and all of the parts thus far specified are of ordinary construction and operate in the ordinary manner; hence it is unnecessary to specifically describe them.

My improvement relates to the manner of and means for taking up the imperfect side rovings, which are usually thrown to waste, and delivering them to the second breaker to be worked in with the rest of the material.

\Vhen viewing the machine in end View, as

in Fig. 3, the right-hand roving 12 of the rub-' rolls 9 and the left-hand roving 13 from the lower rub-rolls 10 are the scant and imperfect ones which are to be returned. After the roving 13 leaves its rub-rolls 10 it is carried upward and fed through the left-hand end of the upper rub-rolls 9, so that both scant rovings are delivered from the ends of the same rolls to the guide hereinafter described, and so that the roving 13 shall not come in harmful contact with the upper rub-rolls on its passage to said guide. The other rovings being delivered from the machine are not represented. These rovings 12 and 13 are carried upwardly and combined at a central point within the flaring guide 14, from which they pass to an endless belt or apron 15, upon which they are carried overhead to the middle of the worker 16 of the second breaker. This belt 15 is supported upon suitable pulleys 1'7, which pulleys are mounted on suitable brackets or supports 25, the endless belt being driven byf means of a driving-belt running upon the pulley 18, secured to the shaft of one of the pulleys 17--as, for instance, the one shown near the bottom of the sheet in Figs. 1 and 2. The flaring guide 14 (shown separately in Figs. 6 and 7) is made adjustable by means of the slot 19, through which'a screw 27 passes into its support 26, while the bracket is pivoted to said support upon a central bearing-hole 20. Underneath the worker 16 is ashell or guide 21, which is secured by an arm to the bracket that supports the shaft of the pulley 17, and is adjustable upon its bracket by means of the slot and screw 22 and 23, (see Fig. 4,) so as to bring the shell or guide 21 into proper relation to the under side of the worker. The combined rovings 12 and 13, extending upward to the flaring guide 14 and meeting at a central point over the machine, are carried along upon the upper side of the endless belt 15 to the pulley 17 at the breaker end of said belt, from which they fall upon the worker 16,

said worker being covered with card-clothing in the ordinary manner. As they reach the under side of said roller, they are caught by the shell or guide 21 and held in contact with said Worker, so as to insure their being taken up thereby and distributed with the rest of the stock to be fed through the machine in the ordinary manner.

By thus taking the imperfect rovings from each side, bringing them together over the middle of the machine, and delivering them to the middle of the worker of the second breaker they are prevented from going to waste by such simple, inexpensive, and convenient means as not in any way to interfere with the general operation of the machine and so as to render their use practicable.

I am aware that attempts have heretofore been made to return the defective rovings to the second breaker by carrying them under the machine at each side and delivering them at two different points on the main cylinder of the second breaker; but so far as I am aware these devices have not been of such a nature as to be adopted for practical use.

My machine by actual use in due course of business has been demonstrated to be a praciieal and useful machine.

I claim as my invention 1. In combination with a second breaker and a finisher carding-engine, the former provided with a worker 16, the endless belt or apron 15, suspended over the middle of the machine, and the guide 14, for uniting the rovings from opposite sides upon said belt, which latter delivers its rovings to said worker at the middle of its length, substantially as described, and for the purpose specified.

Vided with a worker 16, the endless belt or apron 15, suspended over the middle of the machine, the guide 14, for uniting the rovings from opposite sides upon said belt, which lat ter delivers its rovings to said worker, and the shell or guide 21, substantially as described, and for the purpose specified.

3. In combination with a second breaker and a finisher carding-engine, the former provided with a worker 16, the endless belt or apron 15, suspended over the middle of the machine,- the guide 14, for uniting the rovings from opposite sides upon said belt, whiehlatter delivers its rovings to said worker, the shell or guide 21, and means for holding and releasing said guide for adjusting it with reference to said worker, substantially as described, and for the purpose specified.
